Molybdenite could replace silicon, possibly superior to graphene

Researchers have demonstrated the first logic circuits made from molybdenite, a naturally occurring compound made of molybdenum and sulfide (MoS2). Efforts by researchers show the material can not only replace silicon…

Thats cool. Molybdenite is very similar to graphite in its physical properties. I TA'd Mineralogy a few years ago and students often have a hard time distinguishing the two. Its somewhat easy if they are both side by side, but if you just have 1 hand sample they are tough.
